GQCA0354R9DCT

GQCA0354R9DCT Description

The GQCA0354R9DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 54.9 Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit matching. The ceramic case and gull-wing termination provide robust mechanical stability, while the ±25 ppm/°C temperature coefficient guarantees minimal drift across the -70°C to +125°C operating range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is engineered for reliability in precision analog and digital systems.

GQCA0354R9DCT Features

• High Precision: 0.5% tolerance and ±25 ppm/°C TCR for stable performance in temperature-varying environments.
• Robust Construction: Ceramic substrate and gull-wing SMD termination enhance durability and solderability.
• Isolated Design: 12 resistors with independent isolation (ISOL) reduce crosstalk in multi-channel circuits.
• Space-Efficient: Compact 8.66mm × 6.02mm × 1.47mm QSOP package optimizes PCB real estate.
• Wide Operating Range: Derated power capability up to 125°C suits industrial and automotive-grade applications (though non-PPAP).
• Low Noise: Thin-film technology ensures minimal parasitic effects, critical for high-frequency or sensitive analog designs.
